Abstract
Dry reforming of methane (DRM, CH4 + CO2 → 2H2 + 2CO) offers a promising route for converting two greenhouse gases into valuable syngas. However, conventional thermal catalysis requires extreme temperatures (>800 °C) to overcome high energy barrier, leading to significant energy consumption and catalyst deactivation. Herein, we develop a Pt1–Ni1/CeO2 photothermal catalyst with atomically dispersed Pt1–Ni1 paired active sites for DRM under mild conditions. At 450 °C under light illumination, the catalyst exhibits high H2 and CO production rates of 4.62 and 4.65 mmol gcatalyst–1 min–1, respectively, with a H2/CO ratio close to unity (0.99). Mechanistic investigations reveal that light irradiation induces…
